Abstract
In an accessory detection method for an electronic device, a bias voltage is provided to power a chip of an accessory when the accessory is inserted into an audio jack of the electronic device. An initialization command with a preset format is sent to the chip. The electronic device waits for an accessory identifier (AID) of the accessory from the chip. When the electronic device receives the AID of the accessory from the chip, a set of acoustic parameters corresponding to the received AID of the accessory is generated. The method controls the electronic device to apply the generated set of acoustic parameters.
